Abstract: A display device according to an embodiment of the disclosure includes a timing controller, a scan driver including a plurality of stages connected to a plurality of clock signal lines and generating a plurality of scan signals in response to the scan start signal, a data driver configured to generate a plurality of data signals based on the image data, and a pixel portion including a plurality of pixels. One stage in the scan driver transmits a carry signal to 2n-th next stage. The timing controller selects any one of a normal frequency and low frequencies lower than the normal frequency as a driving frequency based on the input image data, and adjusts a clock duty of the plurality of clock signals so that a time required to output all of the plurality of scan signals during one frame is constant irrespective of the driving frequency.
